Subject[PATCH] drivers/macintosh/smu.c: Mark expected switch fall-through
Mark switch cases where we are expecting to fall through.

This patch fixes the following warning (Building: powerpc):

drivers/macintosh/smu.c: In function 'smu_queue_i2c':
drivers/macintosh/smu.c:854:21: warning: this statement may fall through [-Wimplicit-fallthrough=]
cmd->info.devaddr &= 0xfe;
~~~~~~~~~~~~~~~~~~^~~~~~~
drivers/macintosh/smu.c:855:2: note: here
case SMU_I2C_TRANSFER_STDSUB:
^~~~
